Do you want to just help complete virtio-rtc then? Would be easier than trying to keep two specs in sync.The ACPI version is much more lightweight and doesn't take up a valuable PCI slot#. (I know, you can do virtio without PCI but that's complex in other ways).Hmm, should we support virtio over ACPI? Just asking.Given that we support virtio DT bindings, and the ACPI "PRP0001" device exists with a DSM method which literally returns DT properties, including such properties as "compatible=virtio,mmio" ... do we already?
In a sense, but you are saying that is too complex? Can you elaborate? -- MST
